Speaking at the Television Critics Association summer press tour today (August 1), Fox president Kevin Reilly reiterated that the third episode will deal with writing Finn out of the show, before explaining: "That episode will deal with the incidents directly involved with Cory's passing, [including] drug use."

It has not been confirmed whether the storyline will see Finn die as a result of drugs.

Reilly revealed as well that the departure episode will feature drugs-related public service announcements from Ryan Murphy and cast members, and that proceeds from the installment's music will go towards starting a fund in Monteith's name.

The Fox boss went on to describe Lea Michele as a "pillar of strength" and "an extraordinary human being" in connection with Monteith's passing.

He also discussed the future of the show, commenting: "I would not anticipate it going beyond two more seasons. Look, never say never, but there's two very clear arcs to get to the end and conclude.

"If we discover a new crop of kids and there's some breakout in life, who knows? But right now we're just thinking about two more seasons."

Gleewill return for its fifth season in the US on September 26 with a two-part Beatles episode, followed by Monteith's departure episode, after which it will go on a hiatus that has been confirmed to last three weeks.
